Taking clocks down doesn't drop power consumption significantly...
Any idea how much undervolting would do?

Depends on the box fan. Mine pulls 70w on the low setting and 110w on the high setting. Best used to move air across 4-6 rigs to reduce the hit on efficiency.

But I do have a box fan pulling air across the cards and a wireless bridge, so there's another 30w maybe. :/

Even being optimistic I don't see how the rig could be bellow 300W with these frequencies and voltage. Something is definitely wrong here.
+1. Something is wrong somewhere. Even if AC/DC loss was 0 and MB/CPU was 50W. We are talking <130W per 6990?
Agreed. Even for me this didn't pass the smell test.
I'm looking to add an appliance power meter like this one to get real-time power stats (in Watts so no conversion required) for just the mining rig. Currently the UPS power stats are for the entire rack and I subtract out the current draw for the other components in the rack so the error margin is larger than need be.

I'm jealous of you guys getting 3.XX MH/w and more! Dammit, you're going to make me go buy one of those power-sipping CPUs this weekend

I'm still doing some tuning and will soon make the move to a passively cooled water cooled setup but my current measurements show it ranges from 4.52-2.78 MH/W for a dual 6990 rig with the memory underclocked to 150MHz. I run the fans at 50% during daylight hours to regulate the WAF

The wattage rating is computed from Amps via the current probe of the UPS that provides power to the rig and I am assuming a PF of 1 as the PSU is power factor corrected. I'm still a bit skeptical of these numbers though as the efficiency seems to be implausibly high for the day time...

Whoa, I think I finally beat D&T!!! Except now he has a bunch of BFL Singles
I don't have any singles but you didn't beat me either.
Still 2.86 is pretty impressive.My new rig configuration:
4x5970
3.2 GH/s @ 1080W
3.02 MH/W
That is on 240V circuit, 80-Plus Gold PSU, usb drive running linux, optimized BIOS, underclocked & undervolted sempron, and >3 GH/s per rig.
I am pretty sure it isn't possible to get higher efficiency from a GPU rig without undervolting the GPUs. A 4x7990 (or possibly 3x7990) rig will likely beat that though.
Wouldn't a sempron get you better efficiency?
Probably. This is my gaming rig though
I could probably knock another 50W off by going with a low power CPU, which would put me in the 3.1X MH/w range. But that would mean I'd have to swap CPUs to play games, and that's a big hassle.I'm sure your GPU's love having the clocks and voltages change that much, so often.
Just saying.

Anyway, let's see your mining rig efficiency in MH/j (or MH/w, I'm not sure what the diff is exactly). I added another 5970 to my system and finally figured out how to tune down the CPU cores.
